Repair a Califone 1430K record player plug & speaker

The sound you're hearing could be due to a variety of reasons, such as a loose connection, a malfunctioning component, or a power issue. Here are some steps you can take to troubleshoot the issue:

Check the speaker connections: Ensure that the speaker wires are properly connected to the receiver and the speakers. Make sure that the positive and negative terminals are correctly aligned. You can also try disconnecting and reconnecting the wires to ensure a secure connection.

Check the power source: Ensure that the receiver is plugged into a working power outlet and that the power cord is securely connected to the receiver. You can also try plugging the receiver into a different power outlet to see if that resolves the issue.
Check the volume level: Ensure that the volume level on the receiver is not set too high. High volume levels can cause distortion and other issues.

Reset the receiver: Try resetting the receiver to its default settings. To do this, turn off the receiver and unplug it from the power source. Wait for a few minutes, then plug the receiver back in and turn it on.

If these suggestion don't help, you may have to seek professional repair.

If the B speakers on your Kenwood KR-V8010 receiver are not working while the A speakers are working, there are a few things you can check:

1. Check the speaker connections: Make sure that the B speakers are connected to the receiver properly. Ensure that the speaker wires are connected securely and that the polarity is correct.
2. Check the speaker selector switch: The Kenwood KR-V8010 has a speaker selector switch that allows you to choose between A speakers, B speakers, or both. Make sure that the switch is set to the B speaker position.
3. Check the speaker impedance: Make sure that the impedance of the B speakers is compatible with the receiver. The Kenwood KR-V8010 supports speakers with an impedance of 4 to 16 ohms. If the impedance of the B speakers is too low or too high, it can cause issues with the amplifier.
4. Check the volume level: Make sure that the volume level is not set too low for the B speakers. If the volume level is too low, it may not be noticeable that the B speakers are not working.
5. Check the output settings: The Kenwood KR-V8010 has a few output settings that can affect the sound output. Make sure that the settings for the B speakers are not muted or turned off.

If none of these steps resolve the issue, there may be a problem with the amplifier or the B speaker output circuit. In this case, it may be necessary to take the receiver to a professional for repair or maintenance.

Take the turntable off by removing the "E" clip. Make sure the motor spins - if it does not, it can be taken apart and oiled. The main turntable bearing should turn easily - if not take apart and lube. The idler wheel is the next thing to check - clean the rubber tire with alcohol or rubber rejuvenator and grease the bearing. Also check the motor mounting grommets - if they are bad the steps on the motor pulley won't line up with the idler wheel.
That's about all there is to it!

The arm should have a pin through it that secures it to the bracket that is attached to the arm bearing. There should be a long spring that is used to adjust the tracking force and it is underneath the arm.
The arm can be taken off by taking the player apart, unsoldering the wires from the arm and unscrewing the nut on the turntable bearing.
Because the arm mounts to a soft rubber grommet it should feel a little loose.
Hope this helps.

If the original recording is on low volume then you will get louder sound on the player device while if the recording is at high volume the you get low levels on player. try recording at lower volume settings on the phone. Then when you play it it will sound louder on increased volume.

We need to know what the amp is and its model, what the speakers are, what the enclosure is.

There is a mute switch on the headphone jack, inside the unit. If you feel competent, open it up and replace the jack.

May be the "winding" on the speaker. If it has got damp at some point(you may not notice any on the casing) the cardboard tube that the coil is wound around swells and "rubs" in the speaker. Thus producing a scratching sound. Try connecting to another speaker, just to test and if it sounds fine then that is what it is.

Those are just standard phonograph player characteristics in my experience. You'll hear a tap on the deck because there's essentially a live mic ( the needle ) physically coupled with the record on the turntable and the rest of the phonograph player even though they try to dampen the coupling of the turntable as much as possible. The rumbling noise at high gain is because the turntables being driven by a motor via gears or a belt and creates some  vibration, wich is transmitted through the turntable and picked up by the transducer ( needle ), low frequency rumble, just like a recording studio on a busy street may pick up from road vibration/ noise.

try taking ones apart that have the rumbling and see if theres anything loose inside
